Mission Report and Divers Log should shed some light. If they don't have them then it tells me their dive operation is not up to standards. The initial air pressure of each tank main & pony would be noted and any bottom time adjustments made from that. Should have started with no less than 2700 psi. no more than 15 mins bottom time to come up with 1200 psi in the tank. No deco time necessary only safety stop but not a deal breaker without one. My question is where is the backup regulator kept? Is it on a LGS style necklace under the chin or elsewhere, in any case should be easy reach, that's why you train.
As Andrea states removing FFM should not be a problem just an annoyance. Yes diver should be thinking backup air not the surface. I know because it happened to me on a recovery. It was only in 20 ft but when you are heavy, no air in drysuit and no air to put in bcd try staying on the surface and blow air into your bcd. I was down too long and bells in my head where telling me that but no way to read a gauge because we dive in blackwater. What was most interesting was on my last breath, no warning until it was apparent, some water squirted in around my KM EXO26. I went hmmmm not normal then exhaled, went for a breath nothing to be had. Very different than drills where your tank is turned off. Thinking Oh crap go to pony no big deal wait til I give them some of my mind when I get on the surface, but hey that's why we train. I went for the pony reg but it wasn't there under my chin, now it got interesting. Go for the surface or find the hose/reg, remember I had done a complete exhale. Took awhile but found the reg purged it to make sure it wasn't full of mud from being on the bottom, sweetest air I ever had. Found out the snap buckle had broken and come lose during search, It should have been retired years earlier. Check your gear replace what is worn out and train train train and do it with your eyes closed.
